HEMP-BRAKE.

Specification of Letters Patent.

Application filed June 24, 1914. Serial No. 847,086.

To all whom it may concern:

Beit known that I, ELMER THWAITS, citizen of the United States, residing at Milford, in county of Kosciusko and State of Indiana, have invented certain new and useful Improvements in Hemp-Brakes, of which the following is a specification.

This invention relates to an improvement in hemp brakes, and the object is to provide means for treating the rotten or decomposed hemp.

One of the objections to many machines now in use is that the decomposed or partially decomposed hemp from passing be tween the rollers is cut by the rolls, and it is the object of this invention to provide fluted or corrugated rolls preferably made of wood, which have been found to treat the hemp in the most satisfactory manner without injuring the hemp.

A further object of the invention is to provide means for preventing the hemp from-winding or wrapping about the rolls, as it is generally necessary to cut the hemp from the rolls after it becomes wrapped or wound around a roll.

The invention relates to still other novel features of construction and combinations of parts which will be hereinafter described and pointed out in the claim.

In the accompanying drawings: Figure 1 is a view in front elevation; Fig. 2 is a longitudinal vertical sectional View; Fig. 3 is a transverse sectional view through the rollers; and Fig. 4 is a view in side elevation.

A represents two uprights, mounted upon a suitable base or foundation B. Braces 2, 2 are connected to the base and engage the upper ends of the post, forming two sides for strengthening the posts. Mounted between the posts and journaled therein are two rollers, 3 and 4. The lower roller 3 is capable of only a rotary movement, and connected to one end of the roller is a pulley 5. The upper roller 4 has its trunnions or spindles 6 received in vertical slots 7 formed in the posts to permit of the roller having vertical movement. These rollers are preferably fluted or corrugated. A crossbar 8' is located beneath the upper roller 4, and

is received in vertical slots 7. The ends of the bar are provided with flanges or cross strips 9, 9 which engage the outer surface of the posts A and rest uponv the trunnions or spindles 6 of the roller 4. Coil springs 10, 10 are connected to the posts, and to each of the flanges 9 for holding the upper roller in engagement with the lower roller. The upper roller will move vertically according to the amount of hemp which passes between the-rollers. The movement of the rollers is under the control of the springs 10. A shield 11 is connected to the cross bar 8 and the edges of the shield lie in close proximity to the upper roll for the purpose of preventing any of the hemp from windmg or wrapping about the roll. This shield will move with the roll 4, so that it is always 1n close proximity to the roll and prevents any of the matter from passing about the Patented May so, 1916. i

roll, no matter what the position of the roll may be. Similar shields 12 are supported between the posts or uprights A, and the edges engage, or lie in close proximity to, the lower roll 3 to prevent any of the hemp from wrapping around the roll. A feed table 13 is connected to the braces 2, 2 for feeding the hemp to the rolls. After the hemp has passed between the rolls, ,it is discharged onto the table 14.

From the foregoing, it will be seen that I have provided a very simple apparatus for treating the hemp, and in which the hemp is prevented from passing about the rolls. Furthermore, the upper roll is capable of vertical movement to accommodate the vast quantities of hemp fed through the machine, and the shield is mounted about the roller for preventing the hemp from passing aboi ment.

I claim:

In a hemp brake, the combination with posts having slots therein, of upper and lower rolls, the lower roll journaled between the posts, and the upper roll mounted in the slots, a cross bar mounted in the slots, means onthe cross bar engaging the roll, springs connecting to the cross bar and posts for drawing the upper roll toward t the roller during its move;
